There's a thumbnail view, a detailed view, and a list view. Does the list view truncate the title? I only started using Plex a few days ago but I don't recall it cutting names short when I swapped to the List View for a moment.

I'll check again tonight when I get the opportunity - but I imagine a name would need to be quite long for List View to not be good enough (assuming it doesn't truncate).

Thank you gregmac for checking and reporting in with your findings. :)
